The tricky part is you don't have a motor. It's an unpowered vehicle.

(Caveat is the start, you will be pulled up with a rope, another powered plane or have starter motor to get up once)

You can go thousands of miles without propulsion! IF the weather and wind plays nice.

So you go up with thermals (warm air) or lift from hill sides and go forward by gliding. Repeat with skill and luck.
